76% of UK's top tech and telecoms brands now have mobile-optimized website

Findings of a recent study from the Internet Advertising Bureau illustrate the increased awareness of the marketing potential of apps and mobile technology as more consumers use mobile to access the Internet.

"The IAB's mantra this year is to make mobile mandatory. We believe that by producing this series of sector specific audits we are encouraging brands to get to grips with mobile," said the Internet Advertising Bureau's head of mobile, Alex Kozloff.

"It's no longer OK to ignore mobile - if you're looking at engaging, selling or even driving awareness for your brand amongst your consumers, then you need to be embracing this medium."
